V-Power amplifiers deliver the sound quality that made Alpine famous. Highly efficient power supplies housed in sleek black casings guarantee that these amps stand out in performance and appearance. The thermal management system dissipates heat and saves power, so your V-Power amp will run reliably for years to come.

The MRP-F300 4-channel amplifier sends 50 watts RMS to each of your front and rear speakers, or switches to 2-channel mode to power a pair of subwoofers. You can also switch to 3-channel mode, then power a subwoofer with 150 watts RMS while the other two channels power a pair of full-range speakers.

High- and low-pass filters put you in command of the frequencies that reach your speakers, while the bass boost is armed with plenty of low-end punch. Preamp- and speaker-level inputs allow you to connect this amp in almost any vehicle. Let a V-Power amplifier transform the sound of your car's audio system.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Features

Power Supply: The MRP-F300
amplifier's power supply uses MOSFETs to convert DC battery voltage to the
higher DC voltages needed for high power. It supplies positive and negative
voltages around 0V, rather than around 6V as with conventional single-polarity
power supplies. The result is higher power levels and a dynamic range wider by
as much as 10dB.

Inputs: The amplifier offers both line-level and speaker-level inputs
for 4 channels. The supplied speaker-level input harness allows you to connect
this amplifier to a receiver without preamp outputs; aftermarket or factory.

Line Outputs: This amplifier has a pair of non-fading stereo RCA line
outputs. You can use these outputs to daisy-chain another amplifier without
having to run additional signal cables from the receiver.

Terminal Covers: The amp comes with
two
plastic covers that protect and insulate the RCA, power, and speaker connections.
Four supplied
machine screws attach the covers to the amplifier.

Controls

Crossovers: Both front and rear channels have independent high-pass
and low-pass crossovers. The crossover points are continuously variable from
50-400 Hz and the slope of both is 12dB/octave. Each set of channels has a
high-pass/low-pass/off switch.

Subsonic Filter: This amp
utilizes a subsonic filter at 15Hz to eliminate super low frequencies that can rob
power and damage speakers. The subsonic filter operates at all times; it cannot
be turned off.

Bass EQ: The Bass EQ circuit provides a fixed boost of 12dB at 50 Hz
for the rear channels only. The Bass EQ can be turned off and does not function
when the amp's rear-channel crossover is set to high-pass operation.

Connections

Left Side Of Amplifier:

GND (ground): gold-plated screw terminal, 0.33" wide

Battery: gold-plated screw terminal, 0.33" wide

Remote: gold-plated screw terminal, 0.33" wide

Speaker Outputs: gold-plated screw terminals (8), 0.33"
wide

Note: Alpine recommends 8 gauge power and ground wire
(minimum).

Right Side Of Amplifier:

Line Inputs: 2 pair of gold-plated stereo RCA jacks

Line Output: 1 pair of gold-plated stereo RCA jacks

Speaker Level Input: Molex plug input for supplied
4-pin harness

Alpine MRP-F300 4 channel amp

This was my first time purchasing from Crutchfield's outlet. This Alpine "Dent/scratch" item was in perfect condition. I installed it running @ 8ohms 50w x4 RMS to a pair of full range Infinity Reference 4x6" & pair of 6 1/2" 3-way full range speakers. It's now controlled by a Pioneer double din BT audio head unit to replace the stock base stereo. I now look forward to running down to the gas station now just so I may listen to the highs and lows and make my ears bleed! It's awesome.

The only con to this amp is that it requires two pre-amp RCA lines running from the front and rear channels off the head unit if you want fading capability. So my fix for that was to run the pre-amp out off the amp to the rear channel input on the amp. No worries, I just don't have a rear fading channel. When I install a sub, I'll run another preamp line from the head unit and fix it.

Pros:Awesome clarity, old school wire terminals - I like that.
Cost- a ton of power for less than $100

clean and clear 4 channel amp

Written By Willy, queens N.Y. on Tuesday, June 03, 2014

I bought this amp considering it had speaker level inputs and preamp output to connect to another clarion mono amp. I have infinity reference 6.5 components and coaxial in rear. The sound is very precise and clear. This amp makes these speakers loud and I wasn't expecting it. Great bang for the buck.

Great Product

This amp powers all 4 of my alpine speakers without any problems. I have no issues with the amp running hot, and I have plenty of power to run my speakers at high volumes. Alpine is definitely a brand to trust. Be careful when mounting the amp; the brackets can break. So far I have not had any issues with the amp mounted to my rear seat.

Best bang for the Buck

A great choice for powering highs and mids @ 4 channels. won't make your ears bleed but loud and clean. Make sure channels 3&4 are NOT set for SUB OUT option on your head unit. May be why this amp got a few bad reviews. My Wrangler is rockin'! Thanks for the deal Crutchfield

garbage

by far the worst amp I have ever found I read the previous reviews and I just don't understand how can be given 5 stars I'm trying to push 4 speakers and this amp Just Wont do it, it keeps turning down,it was a Install at a local electronic store and they were just amazed As me, is not defective Is just not up for the challenge , when you install an amp is for a reason So why this amp would sound like a regular radio i just dont get it

Pros:looks nice

Cons: not strong enough to push 2 6x9 pionners 60 rms that Should be enough Info

A solid reliable choice in power, great price

I have always had a crush on the smaller Alpine amps. I have used these through the years in a lot of my systems. The key to this or any amp performance is a quality installation with quality wires. I bought this amp b/c it has H/L x-overs on both the front and rear channels. This amp does feature a bass boost function on channels 3 & 4. After some tuning, I decided not to use bass boost on the amp on the kicker 6x9's and use the more adjustable audio functions in the radio, and set the x-overs on the amp as back up if the radio ever got reset. The end caps hide/protect the connections on both sides of the amp. This amp was a good size , but easily fit under the pass seat of my 04 Ram quad cab.

Pros:Reliable Alpine quality, great features for the price. the gains came preset at 50%. After getting the new radio, amp & speakers installed, i tweaked on it for a while and decided to turn off the bass boost in the amp, and set the gains at 50%. This should be plenty of power for most 4 channel mids/highs set up. This amp could provide a reasonable amount of power in a 3 channel setup, (small sub, a pair of separates)

Cons:Be careful when installing them on a uneven truck floor through carpet etc, one of my screws was too short, thus breaking the little plastic mounting tab on one corner of the amp. no big deal, you never know it because of the end caps covering up the mounting screws and connections.

Are you serious?

I have Alpine SPS 610 C component speakers in the front doors and Alpine SPS 610 Coaxial speakers in the rear of my 1996 Tacoma pickup. The speakers are rated 80 Watts RMS. My 22 Watt RMS Kenwood head unit was just not up to the task of bringing out the best in these speakers. I decided to look for an Amp to help these speakers sing. I talked to several of the extremely helpful CSRs at Crutchfiled before making my choice. Some of them suggested the the Alpine MRP-F300. My biggest concern was that the Amp have enough power to push the 80 Watt RMS Alpine speakers. I am not talking about blowing out my neighbors but giving me strong, clear sound. I was not sure the Alpine MRP-F300 at 50 Watts RMS would have enough UUUMPH. I finally talked to Marshall who listened very intently to what I wanted. After a thorough discussion of my system and what I was trying to accomplish both now and as I add a sub he agreed the Alpine MRP-F300 Amp was a good fit. So I tore everything out of my truck cab and wired it for the amp with great anticipation. The moment of truth came when I fired up my system with Joe Walsh's Funk #49. I was BLOWN AWAY! I have been listening to this song since it was first cut and I was now hearing nuisances I had never heard before, not just loud but clear. Are you serious? I would have never thought that this 50 Watt Amp would make these 80 Watt speakers sing so beautifully. But it overwhelmingly does. Get one of these amps while they are still available!

Alpine MRP-F300

I drive a 50 year old car as my daily driver. It's a 1963 VW Beetle. From the factory it had a radio delete plate, and I didn't want to change the dash or have to listen to commercials or dj chatter .... So I bought this little amp and was able to hide it and the speakers and just plug it up to my Iphone when I'm in the car.... Works great..!!! If your going for some record breaking db level, this may not be the amp for you...., but it's plenty loud for me. My wife and kids all keep telling me to turn it down... This amp small = great Plenty of power = great Since I've been running it it's been cool or warm to the touch, not hot at all...= great Price = great I could not be happier !!!!

Pros:Small, cheap, Quality brand, works great,

Cons:I have nothing bad to say about this amp or the service from Crutchfield....

crisp clear sound on a budget

Within all honesty alpine has blown me away with this one. They are able to pack so much power into such a small amp thats its amazing. I was running a r300-4 by rockford and let me tell you this one beats it out of the water. This thing took 6 hours of abuse and still ran pretty cool. This is a bargain for the price!

Good enough for my needs

A good overall buy especially since it was discounted. Sounds great on my four infinity ref-8602cfx speakers and no complaints. Great adjustability as well. Gets warm when it's played at loud volumes for a while but I haven't ran into any issues yet.

Mighty Amp, Small Size

I purchased this amp to replace an aging Orion 5 channel that had served it's purpose after 10 years and two different cars. I was replacing the complete sound system and wanted a reliable amp to power my separates front and rear. My old amp was monster in size, and always ran hot. I know of Alpine's reputation as a leader in this field. I reviewed the amp extensively at a local vendor and read review after review before making a final decision. I ordered it and had free 2 day shipping, giving me enough time to prep my vehicle for the install. Install was a breeze, setting it up alongside the 2 Alpine MRV-M500 amps for my subs.

Overall I am very satisfied with my experience with Crutchfield, prices are competitive. They are very knowledgeable in providing full details of products.

As for the amp, I am currently waiting on sound deadening for my car, and going to do a similar install on my brother' car in the coming week(end).

4-Channel Use

Recommended by the Crutchfield staff. Absolutely no clue how to upgrade my sound. Kept my factory HU, upgraded door speakers and added a mono amp/sub. Powers my speakers amazingly. Max volume before speakers, 33. I can actually surpass that volume at 15. A very noticeable cleaner and more quality sound. Would recommend to any person wanting to add power to their speakers at a very reasonable price.

Great amp for what I was looking for

Received the amp DOA with the front channel. Crutchfield's service team sent a replacement right a way. "Thank you Crutchield". The replacement works like a charm. I have always used Alpine amps without hesitation due to their performance. This amp delivers for the low price. I am an audiophile listener at home. And this amp does just fine.

like it

Very nice, speakers are much louder and really clean. There isn't a volume that sub over powers the mid/highs like when my head unit was powering them. sub:Kicker CVR154 w/ Fosgate P400-1 speaker: Rockford Fosgate PRIME R1693 & Punch P132

Alpine Mrp-F300

Well built unit would have come with a 5 star rating if there had been a wiring kit available mainly a 70 amp fuse, a remote cable and grounding strap

Pros:Excellent value. discount on manufacturers retail price , excellent customer service which then recommended a full price replacement. Not really in my budget so will have to wait and see if the recommended unit goes on sale or the customer service will discount the recommended replacement.

Cons:Too big for my application wish all dimensions were displayed on the website and no available wiring kit

Nice Amp to Wake up your stereo!

I have purchased 2 of these in recent years and really been satisfied with each of the vehicles I installed them in. Adds a nice punch to an aftermarket head unit. I may not win any contests, but I love the good Clean Sound. Love my Alpines!!

Pros:Adds a Nice Punch in a compact space and at a Great Price. Very satisfied.

Good amp for the money

Written By Josh, Tn on Wednesday, January 08, 2014

Purchased this amp to run my infinity kappa compinetns in the front and kappa coaxials in the rear of my 06 tacoma. Running it off of a premier head unit with 4 volt output with internal MOSFET amp. This amp is clean with no noise no pops or thumps of any kind. I can crank it further than what my ears can handle. It also fit Nicole under my driver seat of my tacoma access cab with no trouble at all and isn't even visible. I was nervous about buying this amp due to the cheap price but man am I glad I did.

Solid amp for the price

This has been a great amp. I installed it in my wifes 2012 Hyundai Elantra to run some Infinity Reference series components in the front doors and Kicker coaxials in the rear. Sound is loud and clear. My wife listens to it pretty loud during her 45 minute commute and even during scorching summer temperatures it has never overheated.

Pros:Great amp for the price range, looks really good with end caps to conceal wiring.

Amazing clarity to aftermarket speakers!

One of my door speakers blew in my 2002 Mustang GT with the Mach 460, so I just decided to replace the whole system since you can't find OEM replacement parts for the Mach 460 anymore. I replaced the 2 factory amps with just one of these amps and WOW did it really help wake up all 4 speakers. I also replaced all 4 speakers with Kicker CS68 speakers, and I also replaced the stock head unit with an Alpine HD137BT head unit. This amp went great with all the other new components. All the other 4 channel amps that I looked at were more expensive and I couldn't be happier with my purchase. Don't ever hesitate to buy anything Alpine, they're always #1 to me when choosing car audio products. My system now sounds 100 times better than the original Mach 460.

Pros:Provides great power to all 4 speakers. Adds much more bass to all Speakers. Blends in well with the carpet in my trunk.

powering 4 JBL GTO 6.5 speakers

I recently updated my stock HU with a Kenwood and replaced my stock speakers with 4 JBL GTO 6.5 3-way speakers. They sounded really nice without the amp powering them, but WOW...when I installed the amp to all 4 speakers the sound really increased in quality. Everything is crystal clear and even the bass is much improved with the smaller speakers I don't think I'll put in any kind of sub. My speakers are 2 ohm so these actually put out 75 watts RMS to 2 ohm speakers which is perfect for the speakers that I have.

Great History

Written By Chris L, Richmond, VA on Wednesday, December 18, 2013

This is a great little amp and for the price is a steal! I purchased my first one a few years ago and had it driving two Alpine type R 12's in a 96 Landcruiser. It was waaay more than I needed but I didn't find myself downsizing the system. That same amp is driving 4 10" JL Subs now in the same vehicle driven and listened to everyday by my brother. Reliable.

This purchase was for my 4Runner and driving a 2-ohm JL W3 10" sub. It's a perfect match for power, small footprint and easy to tune. It would be nice if it had a parametric adjustment to the boost but that's pretty picky in the price range.

great amp and great service

I have ordered from Crutchfield many times and they not only have awesome pricing, and fast delivery, but anytime I have a questions their customer service reps and tech team went above and beyond. I've wanted this amp for a while. I signed up for their emails and when I saw the deal on this, I jumped on it. I love dealing with them and I LOVE this amp!

Price point for Success

I do not know a whole lot about what makes a good amp for normal speakers. But i tell you the customer service they run here really know their stuff. So i gotta say when i plugged everything in which was a breeze~ i was really blown away by the fact it was clear sharp and loud. :) I have my amp Gaines turned Down to basically nothing when i crank my radio it really does shine.

Good, clean power

Great amp for the money. Delivers more than enough power to my 4 Boston Acoustics 6x8's (each rated at 50 watts rms). The beauty in this amp is the ability to play at 75 watts x4 (2 ohms) or bridge it and get more power. High and low pass filters mean you get exactly the sound you want coming from each speaker. Cranking the gain results in crazy volumes, at least in my speakers. This amp makes me question whether or not my speakers can really handle 160 watts peak. I have to put the gain down a lot to be able to use the full volume range of my head unit without distortion. I ended up raising the gain and only using volumes 1-30 on the unit (goes to 50). Other than the great power, this amp transfers great quality as well. It also looks good, and is small enough to fit under a seat or anywhere else, really. Installation was a little tricky, considering i had to use connectors on every wire (may have been my fault for using too thick of speaker wire, though.

MRP-F300

Finally my speakers and amps are installed. I'm running 4 Polk 571's and 2 1001's through the MRP-F300 at 2 ohms. Infinity BassLink completes the ensemble. The Alpine powers those speakers with no issues. I'll spare any boring details as those that know Alpine, know quality. If your running speakers off just the head unit, the Alpine will provide quite a surprise in the boost of sound quality. The professional I had install the system had nothing but positive comments. Special thanks to CRUTCHFIELD for many hours of patience in answering ALL of my questions and providing advice on having a solid setup without breaking the bank. MY SYSTEM RIPS.

sweet amp

I have this amp installed in a 2012 ford f-150 super crew. Its mounted under my front passenger seat powering 4 memphis m-class 5x7" coax. speakers ( with the external crossovers). It is running off of my factory deck so i used some PAC line converters. This amp make my speakers scream clarity. The speakers are rated for 50w rms and that is what the amp pushes. I could not ask for better. There is not much room under my seats to mount an amp but it def. fit with a piece of painted black 3/4" mdf board that the amp is screwed down to (had to lift the amp a little for the speaker terminals to clear the seat mounts on the floor). Installs clean and neat. I also have a mrp-m500 pushing one 10" phoenix gold in a custom ported box that is under the driverside rear seat. There was just enough room to mount the amp on the passenger side under the rear seat. All in all the whole package is awsome. Oh and just to help, so you do not have a head ache if you decide to install an aftermarket amp on a factory deck, go and get yourself what is called add a circuit or add a fuse and install that inplace of a fuse in you panel that works with the ignition. There is a wire that comes off it that can be hooked up to the remote wire to turn that amp on and off, and you stab you previous fuse into that and if you would like you can install another fuse for the remote wire there are two slots. Thanks Crutchfield for that tip it helped out!!!

Pros:sounds awsome, small size, plenty of power

Cons:does not accept 4ga. power and ground wire you will have to somehow find some connectors or clip back the wire to fit in the terminal

Worth way more than I paid for it!

I bought this on sale. I wasn't even going to buy an amp because I was just going to upgrade my stock deck to a low end Kenwood and run off deck power, but the deal was too good to pass up, so I bought them both. I initially just used this as a 4 channel amp to power four 6 1/2" Eclipse speakers that came with the car when I bought it. I only turned the gain knob up maybe an 1/8 of the way before it was too much power to the speakers, but the sound quality and volume was 100% better than the stock deck. Out of curiosity, and the search for just a little more low end, I picked up a pawn shop Kenwood 10" sub for $30. I put all four 6 1/2s on channels 1 and 2, and bridged the sub on to 3 and 4(after a call to Crutchfield to check and see if technically could, of course). WOW! The Eclipse speakers, that sounded like they were blown with the stock deck, got even clearer and louder and the sub pumps! I think this is the clearest, most balanced system I have ever put together in 20 years. Not the loudest, but for a total of $260 (deck, amp, sub), I could not be happier.

Great purchase all around.

What a deal on a great amp. Running an Alpine component set and 6.5" coax, coupled with a 500x1 Alpine, this car really rocks. Easy install, great sound, barely even gets warm under heavy use. Thanks to Crutchfield for help getting all the proper installation materials. 100% satisfied.

Powerful compact amp!

I replaced my old worn out kicker ix404 and wow what a difference! The amp is powering 2 component speakers and 2 full range and the sound clarity is phenomenal. The kicker was a good amp but I was pleasantly surprised with how much power this little amp packs for such a small amp. Thanks crutchfield!

Pros:Sound clarity, power, and price.

Cons:No treble mid or bass adjustments on amp, but the eq on my cda 105 takes care of most of the work

Alpine MRP-F300 - solid amp

If you are looking for a solid 4-channel amp, then the Alpine MRP-F300 is it. Don't be fooled by 50 watts RMS, the Alpine MRP-F300, tuned correctly, can max-out any set of speakers' dBs, mids and tweets, and turn'em into a gut wrenching, eardrum piercing experience. The adjustment features are perhaps one of the best things about the Alpine MRP-F300, with total control of filters, crossovers, and gain, there is no reason why you can't get the exact sound you're looking for, plus, spec-for-spec, you can't beat the price of this 4-channal amp. Need proof, take it from me, I ought to know, this is the second Alpine MRP-F300 I've purchased.

never had a problem with alpines amps

I love this amp.Easy install because of its small size,easy to tune,looks great.The only thing is the i wish it had the terminals that you run a set screw into the wire. other than that yes it powers everything great.using focal polyglass cvx 100 4 inch speakers in combination,by the way,they sound amazing....thanks crutchfield for suppling the amp at a great price and with great customer service,and thank you alpine for continuing to make a great product

Very nice amp

I am using this amp for my 2003 ford ranger. I changed the cabin speakers for the Kicker 5x8 factory replacement and this amp does a very nice job of powering them, it sounds great. Very nice amp for the price. Have had absolutely no trouble with any part of this amp and it sounds great.

Great little amp

This is a great little amp that fit nicely tucked away in my trunk. I am running 2 Pioneer 6x9s and 2 Pioneer 61/2s in my Honda Accord coupe and it sounds like I have a full blown system. This amp really pushes my speakers hard with clear powerful highs and rumbling lows that shake my rear view mirror like a sub is in the trunk. I would definitely recommend this amp to someone that wants to upgrade their stock system to something that really rocks.
